摘要

PROBLEM TO BE SOLVED: To provide a commercially advantageous ring-opening metathesis polymerization catalyst.;SOLUTION: The ring-opening metathesis polymerization catalyst comprises (A) a transition metal complex represented by general formula (1) below, (B) at least one compound selected from among amines, pyridines, phosphines, ethers and thioethers, and (C) an alkyl metal compound. LM(X¹)_l(X²)_mY_n (I) (wherein L is a tridentate anionic ligand represented by general formula: RQ(Pz¹)_i(Pz²)_3-i (wherein R is a hydrogen atom, a halogen atom, a hydrocarbon group or the like; Q is boron or the like; Pz¹ is a pyrazolyl group having at least its 3-position substituted with an alkyl group or the like; Pz² is an unsubstituted or substituted pyrazolyl group; and i is an integer of 1-3), or a neutral ligand; M is a transition metal atom selected from group 5 metals of the periodic table; X¹ and X² are each a hydrogen atom, a halogen atom, a hydrocarbon or the like; Y is a neutral ligand having an electron-donating group; l+m is a numerical value satisfying the valence of M; the plurality of groups represented by X¹ or X² can be linked together to form a ring; and n is an integer of 0-3).;COPYRIGHT: (C)2009,JPO&INPIT
